Johns Hopkins team examines Kepler’s supernova using NASA’s three Great Observatories
On the night of October 9, 1604, sky watchers – including Johannes Kepler, an astronomer best known for discovering the laws of planetary motion – were startled by the sudden appearance in the western sky of a "new star" which rivaled the brilliance of the nearby planets. Now, exactly 400 years later, a pair of astronomers at The Johns Hopkins University is using NASA’s three Great Observatories to unravel still-mysterious aspects of the remains of this supernova, the last such object seen to explode in our Milky Way galaxy.
When this bright object – now called "Kepler’s supernova remnant" – appeared alongside Jupiter, Mars, and Saturn on that long-ago October evening, observers had only their naked eyes with which to study it because the telescope would not be invented for another four years. Johns Hopkins University astronomers Ravi Sankrit and William P. Blair, however, have the combined abilities of the Spitzer Space Telescope, the Hubble Space Telescope, and the Chandra X-ray Observatory at their disposal, and are using them to analyze the continuously expanding supernova remnant’s appearance three ways: in infrared radiation, visible light and X-rays.

Artificial agent designs quantum experiments
19.01.2018 | Universität Innsbruck
On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
